命名空间是 Kubernetes 为了在同一物理集群上支持多个虚拟集群而使用的一种抽象。

<!--more--> 

<!--
Namespaces are used to organize objects in a cluster and provide a way to divide cluster resources. Names of resources need to be unique within a namespace, but not across namespaces.
-->

命名空间用来组织集群中对象，并为集群资源划分提供了一种方法。同一命名空间内的资源名称必须唯一，但跨命名空间时不作要求。
